基于连接概率的VANETs路由协议研究
Research on VANETs routing protocol based on connection probability
摘要
Abstract
The communication connection among vehicles of the vehicular Ad Hoc networks(VANETs)is analyzed in this paper. It is assume that the time interval for the vehicles entering into the highway is subordinated to Poisson distribution,and then performance of the communication connection among vehicles is analyzed. The closed⁃form expression of communication connection probability composed of n vehicles is deduced,and the expectation values of CLS (cluster size) and CLL (cluster length) to maintain a certain connection probability are analyzed. The impact of transmission range and density of vehicles on the connection is discussed. The critical value of vehicles′ transmission range which can satisfy a certain connection probability is deduced. The connectivity probabilistic routing protocol(CPRP)is proposed to select the path with big connection probability as the data transmission path. The simulation results show that the proposed CPRP can improve the data packet delivery ratio, end⁃to⁃end transmission delay and throughput performance.关键词
